ABSTRACT

An apparatus for measuring dimension and weight is provided. In one implementation, the apparatus comprises a dimensioner, a force sensing device, and a portable control module. The dimensioner, which is mounted on headgear or body wear to be worn on the head or body of a user, is configured to determine dimensions of an object. The force sensing device, which is incorporated into footwear to be worn on at least one foot of the user, is configured to measure a force acting on a bottom portion of the footwear. The portable control unit includes a dimension input module configured to receive signals from the dimensioner indicative of the dimensions of the object and further includes a weight input module configured to receive signals from the force sensing device indicative of the weight of the object.

FIELD OF THE INVENTION

The present invention relates to measuring various parameters of an object, and more particularly relates to a metrological apparatus that can be worn by a user.

BACKGROUND

Before shipping a parcel, package delivery companies normally measure certain parameters of the parcel to determine a shipping cost to be paid by the customer. For example, weight is one of the main parameters to be determined for calculating cost. In a typical logistics environment, electrical scales are normally used for measuring weight. Other parameters to be measured are the dimensions of the parcel, including, for example, length, width, and height for a parcel having a rectangular shape. For measuring dimensions, a tape measure, yard stick, or other measurement device may be used.

Devices known as dimensioners have become more commonplace in some logistics environments. A dimensioner, or volume dimensioner, is a device that uses a range camera to optically scan a parcel to obtain values indicative of the distance to various points on one or more surfaces of the parcel. From these distance values, the dimensioner can determine the length, width, and height of a rectangular package, determine the length and diameter of a cylindrical package, or determine other dimensional parameters for packages having other shapes. Although some dimensioners may operate from a fixed location along a conveyor system, other dimensioners can be carried by hand and maneuvered to an ideal position to allow the device to view multiple sides of a parcel at once.

According to typical equipment that may be used in many package delivery companies, an employee may be required to place a package on a scale to measure the weight. Then, in order to measure dimensions, the employee may use a tape measure, an electronic tape measure device, or a measuring stick to manually measure the dimensions of the package, or the employee may alternatively use a handheld dimensioner to obtain the dimensions. The measured weight and dimensional information may then be entered into a device for calculating the shipping costs based on one or both of the weight and dimension values.

Such a process can be time-consuming for an employee in a package delivery facility, especially if several packages are to be measured and shipped. Therefore, a need exists for an apparatus that can be used to simplify the process of quickly measuring multiple parameters of a package to be shipped.

SUMMARY

Accordingly, in one aspect, the present invention embraces an apparatus for measuring dimension and weight. The apparatus comprises a dimensioner, a force sensing device, and a portable control module. The dimensioner is mounted on headgear or body wear to be worn on the head or body of a user and is configured to determine dimensions of an object. The force sensing device is incorporated into footwear to be worn on at least one foot of the user and is configured to measure a force acting on a bottom or front portion of the footwear. The portable control unit includes a dimension input module configured to receive signals from the dimensioner indicative of the dimensions of the object. The portable control unit further includes a weight input module configured to receive signals from the force sensing device indicative of the weight of the object (e.g., when supported by the user).

In another exemplary embodiment, a method of creating an apparatus for measuring multiple types of parameters is provided. The method comprises the step of mounting a first device on headgear or body wear to be worn by a user, wherein the first device is configured to measure dimensions of an object. The method also includes the step of mounting a second device on footwear to be worn by the user, wherein the second device is configured to measure weight of the object. Also, the method includes providing a control unit configured to be attached to a belt or clothing of the user. The control unit is configured to receive dimension data from the first device regarding the dimensions of the object and receive weight data from the second device regarding the weight of the object.

The foregoing illustrative summary, as well as other exemplary objectives and/or advantages of the invention, and the manner in which the same are accomplished, are further explained within the following detailed description and its accompanying drawings.

DETAILED DESCRIPTION

The present invention is directed to an apparatus that can be used to measure multiple parameters of a package or box to be delivered. The apparatus can measure dimensions (or volume) of the package and can also measure weight. Normally these two parameters are measured separately in two different processes. In order to reduce the time to measure the two parameters, the present invention integrates the two measuring devices into one apparatus for measuring weight and dimensions. Also, the present invention can simplify the process of measuring package parameters by incorporating the measuring devices into items that can be worn by a user or employee in a logistics environment.

FIG. 1 is a diagram illustrating an embodiment of a wearable metrology apparatus 10. In this exemplary embodiment, the wearable metrology apparatus 10 includes a portable control unit 12, a dimensioner 14 mounted on headgear 16, and a force sensing device 18 mounted on footwear 20. In some embodiments, the portable control unit 12 may be incorporated into either or both of the dimensioner 14 and force sensing device 18. The headgear 16 is configured to be worn on the head of a user 22 and the footwear 20 is configured to be worn on one or both feet of the user 22. In some embodiments, the dimensioner 14 may instead be mounted on body wear (not shown) that is worn on the body of the user 22. According to other embodiments, the dimensioner 14 can be removably mounted on the headgear 16 or body wear so that the user can remove the dimensioner 14 and operate the device by hand. The user 22, for example, may be an employee of a logistics or package delivery company.

Also, the force sensing device 18 may operate in conjunction with a muscle performance sensor (not shown). The muscle performance sensor may be configured to measure the muscle function of the arm or leg muscles of the user 22 while lifting a package. The force sensed by the force sensing device 18 and the muscle activity sensed by the muscle performance sensor can be analyzed together to achieve a more accurate measurement of weight. Muscle activity can also be monitored to ensure the proper lifting techniques are being used by the user 22 to prevent injuries.

The portable control unit 12 may include a clip, clamp, strap, pin, adhesive, hook and loop fasteners, and/or other types of connection or adhesion elements configured to be attached to the belt or clothing of the user 22 and/or wrapped around the waist, arm, ankle, or other body part of the user 22. In some embodiments, the portable control unit 12 may be attached to or formed in the headgear 16 and/or footwear 20. The portable control unit 12 is configured to communicate with the dimensioner 14, particularly to receive calculations of the dimensions of a package. In some embodiments, the portable control unit 12 may instead receive optical signals that can be utilized by the portable control unit 12 to calculate the dimensions of the package.

In addition to receiving input regarding the dimensions of the package, the portable control unit 12 is also configured to communicate with the force sensing device 18, particularly to receive calculations of the weight of the package. In some embodiments, the portable control unit 12 may instead receive signals indicative of parameters that can be utilized by the portable control unit 12 to calculate the weight of the package.

The portable control unit 12 communicates with the dimensioner 14 along a first channel 24 and communicates with the force sensing device 18 along a second channel 26. The first and second channels 24, 26 may be wired and/or wireless channels.

In one embodiment, the channels 24, 26 may include transmission lines (not shown) connecting the portable control unit 12 with the dimensioner 14 and/or force sensing device 18. The transmission lines may be clipped to an outside portion of the clothing of the user 22 or may run underneath a layer of clothing of the user 22. By using transmission lines in the present invention, the portable control unit 12 only receives signals from the coupled dimensioner 14 and force sensing device 18 without the possibility of receiving weight and dimension data from unrelated measuring devices.

According to another embodiment, the channels 24, 26 may be wireless transmission channels. When wireless transmission channels are used for communication, the portable control unit 12, dimensioner 14, and force sensing device 18 may include short range (e.g., Bluetooth) transceiving components.

When wireless transmission is used in the present invention, the various transceiving components may be configured to request identifying information from the other components and to provide such identifying information upon request. Such an identification protocol may be used to ensure that the components associated with one particular package are being used together and to avoid false measurements from other metrology apparatuses being used for other packages.

Therefore, one specific dimensioner 14 and one specific force sensing device 18 are configured to be used together for measuring the different parameters of the same package. These parameters are communicated to the portable control unit 12, which can process the weight and dimension data of the specific package.

Once the weight and dimension values are determined for the particular package, the portable control unit 12 is configured to communicate the values, along with an identification of the particular package, to a host computer 28. The identification of the package may be in the form of barcode information, for example. Therefore, the dimensioner 14 may include a barcode reader for reading a barcode located on the package. The host computer 28 may also receive measurement values with respect to a plurality of other packages from other wearable metrology apparatuses 10 or other measurement systems or devices. In other embodiments, a host computer may be omitted in the system and the portable control unit 12 may be configured as a specialized handheld computer that performs the functions of the host computer 28 as mentioned herein.

FIG. 2 is a block diagram illustrating an embodiment of the portable control unit 12. In this embodiment, the portable control unit 12 may include a processing module 30, a storage module 32, a user input module 34, a dimension input module 36, a weight input module 38, a host interface module 40, and a user output module 42.

The processing module 30 may include one or more processors, microprocessors, and/or other processing elements for controlling the operations and functions of the portable control unit 12. The storage module 32 may include any suitable combination of volatile and non-volatile memory. The storage module 32 may be configured to store software and/or firmware including programming logic to enable the processing module 30 to perform the various operations of the portable control unit 12.

Inputs may be provided to the processing module 30 via one or more of the user input module 34, dimension input module 36, and weight input module 38. The user input module 34 may include any combination of keypads, touchscreens, buttons, switches, and/or other elements for entering data or commands. In some embodiments, the user input module 34 may include an audio input for receiving voice input from the user 22. With voice input, the processing module 30 may utilize voice recognition software, which may be stored in the storage module 32.

The dimension input module 36 may include any suitable components for receiving dimension data via channel 24 from the dimensioner 14 shown in FIG. 1. As mentioned above, dimension data may be communicated by wired or wireless means. When communication is made via wired transmission lines, the dimension input module 36 may include one or more male or female electrical connectors, such as phone jacks, phono jacks, DIN connectors, mini-DIN connectors, cat-5 connectors, XLR connectors, BNC connectors, D-sub connectors, or other suitable types of connectors. When communication over channel 24 utilizes a short range wireless protocol, the dimension input module 36 may include a suitable transceiver for transmitting and receiving signals over the short range.

Similarly, the weight input module 38 of the portable control unit 12 may include any suitable components for communicating with the force sensing device 18 shown in FIG. 1 via channel 26. Data regarding the parameter of weight can be communicated via wired or wireless means across the channel 26. For wired communication, the weight input module 38 may include one or more male or female electrical connectors of any suitable type. The weight input module 38 may alternatively include transceiving circuitry for enabling wireless communication with the force sensing device 18.

Regarding outputs of the portable control unit 12, FIG. 2 shows the host interface module 40 and the user output module 42. The host interface module 40 may include any suitable type of short range transceiving elements for transmitting and receiving wireless signals with the host computer 28, as shown in FIG. 1. For example, the host interface module 40 may operate in accordance with the IEEE 802.11 protocol (e.g., frequency hopping, orthogonal frequency division multiplexing, Wi-Fi, etc.) and/or in accordance with the IEEE 802.15 protocol (e.g., wireless personal area network, Bluetooth, etc.).

The host interface module 40 may transmit both the dimension data and weight data regarding a particular package to the host computer 28. With this information, the host computer 28 can store and manage parameters of multiple packages and assist in the monitoring and tracking of packages as they are being shipped from one location to another.

It should be noted that the transceiving elements for communicating with the dimensioner 14, force sensing device 18, and host computer 28 may be combined into one unit. In other embodiments, communication with the host computer 28 may be accomplished with a different wireless communication system and/or different communication protocol.

Still referring to FIG. 2, the portable control unit 12 may include a user output module 42 for providing signals to the user 22. For example, with a voice activated system, the user output module 42 may be configured to provide voice commands to the user 22. Other audible outputs may include beeps, chimes, buzzers, or other sounds or noises to communicate acceptable or unacceptable inputs received, completion of a measurement, or other conditions or situations. Also, the user output module 42 may include a visual display device, such as a display screen for showing results of measurements or other types of information.

FIG. 3 is a diagram illustrating an implementation of the wearable metrology apparatus 10 of FIG. 1. When the user 22 wears the headgear 16 equipped with the dimensioner 14 and the footwear 20 equipped with the force sensing device 18, the user 22 can utilize the wearable metrology apparatus 10 essentially hands-free to make the different types of measurements. In this implementation, the user 22 is able to obtain multiple measurable parameters simultaneously. As shown in FIG. 3, the user 22 holds a package 50 to be measured while standing with his or her feet 52 on the ground 54.

The force sensing device 18 may include sensors incorporated in any portion of the footwear 20, particularly underneath the weight of the user 22 when standing. In some embodiments, the force sensing device 18 may be incorporated in a portion of the footwear 20 under the user's toes and balls of his or her feet 52.

In addition to the sensors for measuring weight, the force sensing device 18 may further include other pressure sensors placed in or on any part of the footwear 20. The additional pressure sensors may be used by the user 22 for entering commands or signals. For example, one or two pressure sensors may be positioned between the pair of shoes and may receive a signal when the user 22 taps the shoes together. In another embodiment, a pressure sensor in one or both of the heels of the footwear 20 may receive a signal when the user 22 taps the heel on the ground 54. The sensors particularly designed for measuring weight can also be used to detect a light tap. These and other methods may be used to allow the user 22 to enter commands.

In addition to foot tapping signals, the wearable metrology apparatus 10 may also include a keypad, buttons, switches, or other input mechanisms on the portable control unit 12. Also, as mentioned above, the headgear 16 may be configured as a headset that is responsive to voice commands.

The portable control unit 12 may include processing functionality to control the system in response to the foot taps or other commands or signals from the user 22. For example, some of the functionality may include turning the apparatus 10 on or off, such as by tapping a certain number of times, pressing a button, or giving a voice command to turn on or turn off. Other functionality may include resetting the system if necessary. Another function may include performing a measurement of one or both of the parameters in response to various user inputs or commands. Also, other commands to confirm a measurement, redo a measurement, scan a bar code, and other inputs may be entered as needed in the measurement process.

After a command is received to start the measurements, the user 22 picks up the package 50. While the weight measurement is being obtained, the user 22 may also turn his or her face toward the package 50 such that the dimensioner 14 can properly scan the package 50 to determine dimensions. In this manner, the user 22 can quickly and easily make multiple measurements at one time with the measuring devices that are incorporated into the headgear 16 (or body wear) and footwear 20 being worn by the user 22. Therefore, the wearable metrology apparatus 10 is an integrated multi-component system that enables multiple simultaneously measurements.

In other embodiments, the user 22 may perform the weight measurement separately from the dimension measurement. For instance, if the user 22 is unable to position his or her head or body such that the dimensioner 14 can view the entire package 50 while the user 22 is holding the package, the user 22 may need to place the package 50 far enough away to allow the dimensioner 14 to properly scan the package 50.

In another situation, the user 22 may be unable to hold the package 50 steady enough to enable the force sensing device 18 to make a proper weight measurement. For example, when the user 22 is not properly balanced or shifts his or her weight significantly, it may be difficult for a weight measurement to be obtained. In this situation, the user 22 may need to place the package 50 on a conventional scale for measurement.

However, for most packages, a user 22 may be able to perform both measurements simultaneously, thereby saving time in the process of making the multiple measurements. Also, by wearing the wearable metrology apparatus 10, the user 22 does not need to carry packages to designated measuring stations or worry about the location of handheld dimensioners that may tend to get misplaced.

According to some embodiments of the present invention, the portable control unit 12 and/or host computer 28 may be configured to track safety information. For example, the total amount of weight lifted by a worker during a certain time period can be tracked. If the weight exceeds a maximum safety limit, an alert can be communicated to the user 22 or to the host computer 28. The portable control unit 12 and/or host computer 28 may also perform other safety functions, such as detecting industrial accidents and responding appropriately.

FIGS. 4-7 show embodiments of various headgear on which the dimensioner 14 can be mounted. As mentioned above, the dimensioner 14 is configured to determine the outer dimensions of a package by the use of a range camera that projects light onto the object and receives feedback indicative of distance data. From the dimensions, the dimensioner 14 can calculate the volume of the package 50. The functionality of determining dimensions and volume may be incorporated entirely in the dimensioner 14 or some of the functionality may be shared with the portable control unit 12. It should also be noted that the dimensioner 14 may be configured with barcode reading components to enable the dimensioner 14 to read a barcode on the package 50. In this way, the identity and other information of the package 50 can be determined electronically.

In some embodiments, the dimensioner 14 may comprise a light projector on one side and a pickup sensor on the other side. The light projector and pickup sensor may be disposed in a single housing. In other embodiments, the dimensioner 14 may include two separate housings, one in which the light projector is disposed and the other in which the pickup sensor is disposed. Although FIGS. 4-7 show a single housing for the dimensioner 14, it should be noted that the dimensioner 14 may include two or more housings.

FIG. 4 is a diagram of a hat 60 or cap on which the dimensioner 14 can be permanently or temporarily mounted. In some embodiments, the dimensioner 14 can be sewn into the material of the hat 60 or cap or formed in the bill of the hat 60 or cap. In other embodiments, the dimensioner 14 may include a clip, clamp, pin, hook and loop fasteners, adhesive, or other suitable means for connecting the dimensioner 14 to the hat 60 or cap.

FIG. 5 is a diagram illustrating an embodiment of a headset 64 on which the dimension 14 can be mounted. The headset 64 may include one or more headphones 66 and a microphone 68. The headphones 66 may be used in the present invention to provide commands or other audible output to the user 22. When the wearable metrology apparatus 10 is equipped with voice-recognition software, the microphone 68 of the headset 64 may be used to receive voice commands or other audible input from the user 22.

FIG. 6 is a diagram illustrating an embodiment of a helmet 72 or other protective headgear to be worn by the user 22. In this embodiment, the helmet 72 includes the dimensioner 14 either built into the helmet 72 itself or attached to the helmet 72 in any suitable manner. For example, the helmet 72 and dimensioner 14 may include compatible connection elements for securely attaching the dimensioner 14 to the helmet 72.

In some embodiments, the helmet 72 may include a visor 74 and internal projection device (not shown). The internal projection device of the helmet 72 may be a digital light processing (DLP) display device, which uses digital micro-mirror technology to project information onto an inside surface of the visor 74 to communicate information to the user 22. For example, the internal projection device may display an image of the package with a wireframe image formed around it. In this way, the user can see in real time what view the dimensioner 14 is able to capture. Thus, the user 22 can adjust the position of the package 50 or adjust the direction or tilt of his or her head to get the package 50 within a proper frame for ensuring adequate scanning.

FIG. 7 is a diagram illustrating an embodiment of a pair of glasses 80 on which the dimensioner 14 can be mounted. As mentioned above with respect to the embodiments of FIGS. 4-6, the dimensioner 14 may be permanently or temporarily connected to the glasses 80. The glasses 80 may be protective glasses, goggles, prescription glasses, sunglasses, or other types of eyewear. In some embodiments, the dimensioner 14 may also be equipped with a DLP display device for projecting information onto one or more lenses of the glasses 80.

Although not illustrated in FIGS. 4-7, the dimensioner 14 may also be mounted on or attached to other types of headgear to be worn on the head of the user 22 or body wear to be worn on some part of the body of the user 22. For example, some body wear on which the dimensioner 14 can be mounted may include clothing, clips, clamps, belts, etc. In some alternative embodiments, the dimensioner 14 may be incorporated into a shoulder pad placed on or over one or both of the user's shoulders.

In addition to various embodiments for mounting the dimensioner 14 onto headgear 16 or body wear, it should be recognized that the wearable metrology apparatus 10 may be configured such that the force sensing device 18 can also be incorporated into various types of footwear 20.

FIG. 8 is a diagram illustrating an embodiment of a shoe 86 on which the force sensing device 18 can be mounted. In this embodiment, the shoe 86 may be a safety shoe, work boot, or other type of shoe or boot. It should be recognized that the shoe 86 of FIG. 8 may represent one shoe of a pair of shoes, wherein each shoe is substantially the same, except for being mirror images of each other. In this respect, the force sensing device 18 may include two parts, one part to measure force in the right shoe and the other part to measure force in the left shoe. The force detected in the two shoes can thus be added together to get a total force, as should be understood.

Although FIG. 8 is the only illustrated implementation of incorporating the force sensing device 18 into footwear 20, it should be noted that other implementations may be utilized in the present invention. For example, in addition to shoes and boots, the footwear 20 may also include flexible shoe or footwear covers, over-shoe/footwear attachment, snap-on attachments, insoles, shoe or footwear inserts, or other types of footwear.

In some embodiments, the force sensing device 18 may include a steady state detection unit configured to wait for a steady state when weight is approximately distributed to the two shoes and/or when the weight does not fluctuate significantly.

According to some embodiments, the force sensing device 18 may be positioned near a front portion of the shoes or boots underneath the toes and/or balls (i.e., the padded portions of the soles) of the user's feet 52. Therefore, weight can be measured when the user 22 raises his or her heels off the ground 54 and balances on the balls of his or her feet 52.

It should also be noted that the force sensing device 18 and/or portable control unit 12 may be configured to determine the weight of the user 22 before picking up the package 50 and then determine weight again after the user 22 picks up the package 50. By subtracting out the weight of user 22, the weight of the package 50 can be determined. The force sensing device 18 can therefore be calibrated with the user's weight at the beginning of a shift when the user 22 first puts the footwear 20 on his or her feet. Calibration may also be made at various times throughout the shift to accurately account for variations in the user's weight, particularly if the user 22 eats a meal, removes a layer of clothing during the shift, adds or removes items from the user's pockets, etc. Also, it should be noted that calibration should be performed after the user 22 has already placed the headgear 16 (or body wear) on his or her head (or body) to account for the weight of the dimensioner 14 and headgear 16 (or body wear).
